The Paleolithic or Palaeolithic (/ˌpæliəˈlɪθɪk/) is a period in human prehistory distinguished by the original development of stone tools that covers c. 95% of human technological prehistory.[1] It extends from the earliest known use of stone tools by hominins c. 3.3 million years ago, to the end of the Pleistocene c. 11,650 cal BP.[2]

The Paleolithic is followed in Europe by the Mesolithic, although the date of the transition varies geographically by several thousand years.

During the Paleolithic, hominins grouped together in small societies such as bands, and subsisted by gathering plants and fishing, hunting or scavenging wild animals.[3] The Paleolithic is characterized by the use of knappedstone tools, although at the time humans also used wood and bone tools. Other organic commodities were adapted for use as tools, including leather and vegetable fibers; however, due to their nature, these have not been preserved to any great degree.

About 50,000 years ago, there was a marked increase in the diversity of artifacts. In Africa, bone artifacts and the first art appear in the archaeological record. The first evidence of human fishing is also noted, from artifacts in places such as Blombos cave in South Africa. Archaeologists classify artifacts of the last 50,000 years into many different categories, such as projectile points, engraving tools, knife blades, and drilling and piercing tools.

Humankind gradually evolved from early members of the genus Homo—such as Homo habilis, who used simple stone tools—into anatomicallymodern humans as well as behaviorallymodern humans by the Upper Paleolithic.[4] During the end of the Paleolithic, specifically the Middle and or Upper Paleolithic, humans began to produce the earliest works of art and began to engage in religious and spiritual behavior such as burial and ritual.[5][6] The climate during the Paleolithic consisted of a set of glacial and interglacial periods in which the climate periodically fluctuated between warm and cool temperatures. Archaeological and genetic data suggest that the source populations of Paleolithic humans survived in sparsely wooded areas and dispersed through areas of high primary productivity while avoiding dense forest cover.[7]

By c. 50,000 – c. 40,000 BP, the first humans set foot in Australia. By c. 45,000 BP, humans lived at 61°N latitude in Europe.[8] By c. 30,000 BP, Japan was reached, and by c. 27,000 BP humans were present in Siberia, above the Arctic Circle.[8] At the end of the Upper Paleolithic, a group of humans crossed Beringia and quickly expanded throughout the Americas.[9]

The term "Palaeolithic" was coined by archaeologist John Lubbock in 1865.[10] It derives from Greek: παλαιός, palaios, "old"; and λίθος, lithos, "stone", meaning "old age of the stone" or "Old Stone Age".

The Paleolithic coincides almost exactly with the Pleistocene epoch of geologic time, which lasted from 2.6 million years ago to about 12,000 years ago.[11] This epoch experienced important geographic and climatic changes that affected human societies.

During the preceding Pliocene, continents had continued to drift from possibly as far as 250 km (160 mi) from their present locations to positions only 70 km (43 mi) from their current location. South America became linked to North America through the Isthmus of Panama, bringing a nearly complete end to South America's distinctive marsupial fauna. The formation of the isthmus had major consequences on global temperatures, because warm equatorial ocean currents were cut off, and the cold Arctic and Antarctic waters lowered temperatures in the now-isolated Atlantic Ocean.

Most of Central America formed during the Pliocene to connect the continents of North and South America, allowing fauna from these continents to leave their native habitats and colonize new areas.[12] Africa's collision with Asia created the Mediterranean, cutting off the remnants of the Tethys Ocean. During the Pleistocene, the modern continents were essentially at their present positions; the tectonic plates on which they sit have probably moved at most 100 km (62 mi) from each other since the beginning of the period.[13]

Climates during the Pliocene became cooler and drier, and seasonal, similar to modern climates. Ice sheets grew on Antarctica. The formation of an Arctic ice cap around 3 million years ago is signaled by an abrupt shift in oxygenisotope ratios and ice-rafted cobbles in the North Atlantic and North Pacific Ocean beds.[14] Mid-latitude glaciation probably began before the end of the epoch. The global cooling that occurred during the Pliocene may have spurred on the disappearance of forests and the spread of grasslands and savannas.[12]
The Pleistocene climate was characterized by repeated glacial cycles during which continental glaciers pushed to the 40th parallel in some places. Four major glacial events have been identified, as well as many minor intervening events. A major event is a general glacial excursion, termed a "glacial". Glacials are separated by "interglacials". During a glacial, the glacier experiences minor advances and retreats. The minor excursion is a "stadial"; times between stadials are "interstadials". Each glacial advance tied up huge volumes of water in continental ice sheets 1,500–3,000 m (4,900–9,800 ft) deep, resulting in temporary sea level drops of 100 m (330 ft) or more over the entire surface of the Earth. During interglacial times, such as at present, drowned coastlines were common, mitigated by isostatic or other emergent motion of some regions.

The effects of glaciation were global. Antarctica was ice-bound throughout the Pleistocene and the preceding Pliocene. The Andes were covered in the south by the Patagonian ice cap. There were glaciers in New Zealand and Tasmania. The now decaying glaciers of Mount Kenya, Mount Kilimanjaro, and the Ruwenzori Range in east and central Africa were larger. Glaciers existed in the mountains of Ethiopia and to the west in the Atlas mountains. In the northern hemisphere, many glaciers fused into one. The Cordilleran ice sheet covered the North American northwest; the Laurentide covered the east. The Fenno-Scandian ice sheet covered northern Europe, including Great Britain; the Alpine ice sheet covered the Alps. Scattered domes stretched across Siberia and the Arctic shelf. The northern seas were frozen. During the late Upper Paleolithic (Latest Pleistocene) c. 18,000 BP, the Beringia land bridge between Asia and North America was blocked by ice,[13] which may have prevented early Paleo-Indians such as the Clovis culture from directly crossing Beringia to reach the Americas.

According to Mark Lynas (through collected data), the Pleistocene's overall climate could be characterized as a continuous El Niño with trade winds in the south Pacific weakening or heading east, warm air rising near Peru, warm water spreading from the west Pacific and the Indian Ocean to the east Pacific, and other El Niño markers.[15]

The Paleolithic is often held to finish at the end of the ice age (the end of the Pleistocene epoch), and Earth's climate became warmer. This may have caused or contributed to the extinction of the Pleistocene megafauna, although it is also possible that the late Pleistocene extinctions were (at least in part) caused by other factors such as disease and overhunting by humans.[16][17] New research suggests that the extinction of the woolly mammoth may have been caused by the combined effect of climatic change and human hunting.[17] Scientists suggest that climate change during the end of the Pleistocene caused the mammoths' habitat to shrink in size, resulting in a drop in population. The small populations were then hunted out by Paleolithic humans.[17] The global warming that occurred during the end of the Pleistocene and the beginning of the Holocene may have made it easier for humans to reach mammoth habitats that were previously frozen and inaccessible.[17] Small populations of woolly mammoths survived on isolated Arctic islands, Saint Paul Island and Wrangel Island, until c. 3700 BCE and c. 1700 BCE respectively. The Wrangel Island population became extinct around the same time the island was settled by prehistoric humans.[18] There is no evidence of prehistoric human presence on Saint Paul island (though early human settlements dating as far back as 6500 BCE were found on the nearby Aleutian Islands).[19]

Currently agreed upon classifications as Paleolithic geoclimatic episodes[20]

Nearly all of our knowledge of Paleolithic human culture and way of life comes from archaeology and ethnographic comparisons to modern hunter-gatherer cultures such as the !Kung San who live similarly to their Paleolithic predecessors.[21] The economy of a typical Paleolithic society was a hunter-gatherer economy.[22] Humans hunted wild animals for meat and gathered food, firewood, and materials for their tools, clothes, or shelters.[22]

Human population density was very low, around only one person per square mile.[3] This was most likely due to low body fat, infanticide, women regularly engaging in intense endurance exercise,[23] late weaning of infants, and a nomadic lifestyle.[3] Like contemporary hunter-gatherers, Paleolithic humans enjoyed an abundance of leisure time unparalleled in both Neolithic farming societies and modern industrial societies.[22][24] At the end of the Paleolithic, specifically the Middle and or Upper Paleolithic, humans began to produce works of art such as cave paintings, rock art and jewellery and began to engage in religious behavior such as burial and ritual.[25]

At the beginning of the Paleolithic, hominins were found primarily in eastern Africa, east of the Great Rift Valley. Most known hominin fossils dating earlier than one million years before present are found in this area, particularly in Kenya, Tanzania, and Ethiopia.

By c. 2,000,000 – c. 1,500,000 BP, groups of hominins began leaving Africa and settling southern Europe and Asia. Southern Caucasus was occupied by c. 1,700,000 BP, and northern China was reached by c. 1,660,000 BP. By the end of the Lower Paleolithic, members of the hominin family were living in what is now China, western Indonesia, and, in Europe, around the Mediterranean and as far north as England, southern Germany, and Bulgaria. Their further northward expansion may have been limited by the lack of control of fire: studies of cave settlements in Europe indicate no regular use of fire prior to c. 400,000 – c. 300,000 BP.[26]

East Asian fossils from this period are typically placed in the genus Homo erectus. Very little fossil evidence is available at known Lower Paleolithic sites in Europe, but it is believed that hominins who inhabited these sites were likewise Homo erectus. There is no evidence of hominins in America, Australia, or almost anywhere in Oceania during this time period.

Fates of these early colonists, and their relationships to modern humans, are still subject to debate. According to current archaeological and genetic models, there were at least two notable expansion events subsequent to peopling of Eurasia c. 2,000,000 – c. 1,500,000 BP. Around 500,000 BP a group of early humans, frequently called Homo heidelbergensis, came to Europe from Africa and eventually evolved into Homo neanderthalensis (Neanderthals). In the Middle Paleolithic, Neanderthals were present in the region now occupied by Poland.

Both Homo erectus and Homo neanderthalensis became extinct by the end of the Paleolithic. Descended from Homo Sapiens, the anatomically modern Homo sapiens sapiens emerged in eastern Africa c. 200,000 BP, left Africa around 50,000 BP, and expanded throughout the planet. Multiple hominid groups coexisted for some time in certain locations. Homo neanderthalensis were still found in parts of Eurasia c. 30,000 BP years, and engaged in an unknown degree of interbreeding with Homo sapiens sapiens. DNA studies also suggest an unknown degree of interbreeding between Homo sapiens sapiens and Homo sapiens denisova.[27]

Hominin fossils not belonging either to Homo neanderthalensis or to Homo sapiens species, found in the Altai Mountains and Indonesia, were radiocarbon dated to c. 30,000 – c. 40,000 BP and c. 17,000 BP respectively.

For the duration of the Paleolithic, human populations remained low, especially outside the equatorial region. The entire population of Europe between 16,000 and 11,000 BP likely averaged some 30,000 individuals, and between 40,000 and 16,000 BP, it was even lower at 4,000–6,000 individuals.[28]

Paleolithic humans made tools of stone, bone, and wood.[22] The early paleolithic hominins, Australopithecus, were the first users of stone tools. Excavations in Gona, Ethiopia have produced thousands of artifacts, and through radioisotopic dating and magnetostratigraphy, the sites can be firmly dated to 2.6 million years ago. Evidence shows these early hominins intentionally selected raw materials with good flaking qualities and chose appropriate sized stones for their needs to produce sharp-edged tools for cutting.[29]

The earliest Paleolithic stone tool industry, the Oldowan, began around 2.6 million years ago.[30] It contained tools such as choppers, burins, and stitching awls. It was completely replaced around 250,000 years ago by the more complex Acheulean industry, which was first conceived by Homo ergaster around 1.8–1.65 million years ago.[31] The Acheulean implements completely vanish from the archaeological record around 100,000 years ago and were replaced by more complex Middle Paleolithic tool kits such as the Mousterian and the Aterian industries.[32]

Lower Paleolithic humans used a variety of stone tools, including hand axes and choppers. Although they appear to have used hand axes often, there is disagreement about their use. Interpretations range from cutting and chopping tools, to digging implements, to flaking cores, to the use in traps, and as a purely ritual significance, perhaps in courting behavior. William H. Calvin has suggested that some hand axes could have served as "killer Frisbees" meant to be thrown at a herd of animals at a waterhole so as to stun one of them. There are no indications of hafting, and some artifacts are far too large for that. Thus, a thrown hand axe would not usually have penetrated deeply enough to cause very serious injuries. Nevertheless, it could have been an effective weapon for defense against predators. Choppers and scrapers were likely used for skinning and butchering scavenged animals and sharp-ended sticks were often obtained for digging up edible roots. Presumably, early humans used wooden spears as early as 5 million years ago to hunt small animals, much as their relatives, chimpanzees, have been observed to do in Senegal, Africa.[33] Lower Paleolithic humans constructed shelters, such as the possible wood hut at Terra Amata.

Fire was used by the Lower Paleolithic hominins Homo erectus and Homo ergaster as early as 300,000 to 1.5 million years ago and possibly even earlier by the early Lower Paleolithic (Oldowan) hominin Homo habilis and/or by robust Australopithecines such as Paranthropus.[3] However, the use of fire only became common in the societies of the following Middle Stone Age and Middle Paleolithic.[2] Use of fire reduced mortality rates and provided protection against predators.[34] Early hominins may have begun to cook their food as early as the Lower Paleolithic (c. 1.9 million years ago) or at the latest in the early Middle Paleolithic (c. 250,000 years ago).[35] Some scientists have hypothesized that hominins began cooking food to defrost frozen meat, which would help ensure their survival in cold regions.[35]

The Lower Paleolithic Homo erectus possibly invented rafts (c. 840,000 – c. 800,000 BP) to travel over large bodies of water, which may have allowed a group of Homo erectus to reach the island of Flores and evolve into the small hominin Homo floresiensis. However, this hypothesis is disputed within the anthropological community.[36][37] The possible use of rafts during the Lower Paleolithic may indicate that Lower Paleolithic hominins such as Homo erectus were more advanced than previously believed, and may have even spoken an early form of modern language.[36] Supplementary evidence from Neanderthal and modern human sites located around the Mediterranean Sea, such as Coa de sa Multa (c. 300,000 BP), has also indicated that both Middle and Upper Paleolithic humans used rafts to travel over large bodies of water (i.e. the Mediterranean Sea) for the purpose of colonizing other bodies of land.[36][38]

By around 200,000 BP, Middle Paleolithicstone tool manufacturing spawned a tool making technique known as the prepared-core technique, that was more elaborate than previous Acheulean techniques.[4] This technique increased efficiency by allowing the creation of more controlled and consistent flakes.[4] It allowed Middle Paleolithic humans to create stone tipped spears, which were the earliest composite tools, by hafting sharp, pointy stone flakes onto wooden shafts. In addition to improving tool making methods, the Middle Paleolithic also saw an improvement of the tools themselves that allowed access to a wider variety and amount of food sources. For example, microliths or small stone tools or points were invented around 70,000–65,000 BP and were essential to the invention of bows and spear throwers in the following Upper Paleolithic.[34]

Harpoons were invented and used for the first time during the late Middle Paleolithic (c. 90,000 BP); the invention of these devices brought fish into the human diets, which provided a hedge against starvation and a more abundant food supply.[38][39] Thanks to their technology and their advanced social structures, Paleolithic groups such as the Neanderthals—who had a Middle Paleolithic level of technology—appear to have hunted large game just as well as Upper Paleolithic modern humans.[40] and the Neanderthals in particular may have likewise hunted with projectile weapons.[41] Nonetheless, Neanderthal use of projectile weapons in hunting occurred very rarely (or perhaps never) and the Neanderthals hunted large game animals mostly by ambushing them and attacking them with mêlée weapons such as thrusting spears rather than attacking them from a distance with projectile weapons.[25][42]

During the Upper Paleolithic, further inventions were made, such as the netc. 22,000 or c. 29,000 BP)[34]bolas,[43] the spear thrower (c. 30,000 BP), the bow and arrow (c. 25,000 or c. 30,000 BP)[3] and the oldest example of ceramic art, the Venus of Dolní Věstonice (c. 29,000 – c. 25,000 BCE).[3] Early dogs were domesticated, sometime between 30,000 and 14,000 BP, presumably to aid in hunting.[44] However, the earliest instances of successful domestication of dogs may be much more ancient than this. Evidence from canineDNA collected by Robert K. Wayne suggests that dogs may have been first domesticated in the late Middle Paleolithic around 100,000 BP or perhaps even earlier.[45]

Archaeological evidence from the Dordogne region of France demonstrates that members of the European early Upper Paleolithic culture known as the Aurignacian used calendars (c. 30,000 BP). This was a lunar calendar that was used to document the phases of the moon. Genuine solar calendars did not appear until the Neolithic.[46] Upper Paleolithic cultures were probably able to time the migration of game animals such as wild horses and deer.[47] This ability allowed humans to become efficient hunters and to exploit a wide variety of game animals.[47] Recent research indicates that the Neanderthals timed their hunts and the migrations of game animals long before the beginning of the Upper Paleolithic.[40]

Humans may have taken part in long-distance trade between bands for rare commodities and raw materials (such as stone needed for making tools) as early as 120,000 years ago in Middle Paleolithic.

The social organization of the earliest Paleolithic (Lower Paleolithic) societies remains largely unknown to scientists, though Lower Paleolithic hominins such as Homo habilis and Homo erectus are likely to have had more complex social structures than chimpanzee societies.[48] Late Oldowan/Early Acheulean humans such as Homo ergaster/Homo erectus may have been the first people to invent central campsites or home bases and incorporate them into their foraging and hunting strategies like contemporary hunter-gatherers, possibly as early as 1.7 million years ago;[4] however, the earliest solid evidence for the existence of home bases or central campsites (hearths and shelters) among humans only dates back to 500,000 years ago.[4][dead link]

Similarly, scientists disagree whether Lower Paleolithic humans were largely monogamous or polygynous.[48] In particular, the Provisional model suggests that bipedalism arose in pre-Paleolithic australopithecine societies as an adaptation to monogamous lifestyles; however, other researchers note that sexual dimorphism is more pronounced in Lower Paleolithic humans such as Homo erectus than in modern humans, who are less polygynous than other primates, which suggests that Lower Paleolithic humans had a largely polygynous lifestyle, because species that have the most pronounced sexual dimorphism tend more likely to be polygynous.[49]

Human societies from the Paleolithic to the early Neolithic farming tribes lived without states and organized governments. For most of the Lower Paleolithic, human societies were possibly more hierarchical than their Middle and Upper Paleolithic descendants, and probably were not grouped into bands,[50] though during the end of the Lower Paleolithic, the latest populations of the hominin Homo erectus may have begun living in small-scale (possibly egalitarian) bands similar to both Middle and Upper Paleolithic societies and modern hunter-gatherers.[50]

Middle Paleolithic societies, unlike Lower Paleolithic and early Neolithic ones, consisted of bands that ranged from 20–30 or 25–100 members and were usually nomadic.[3][50] These bands were formed by several families. Bands sometimes joined together into larger "macrobands" for activities such as acquiring mates and celebrations or where resources were abundant.[3] By the end of the Paleolithic era (c. 10,000 BP), people began to settle down into permanent locations, and began to rely on agriculture for sustenance in many locations. Much evidence exists that humans took part in long-distance trade between bands for rare commodities (such as ochre, which was often used for religious purposes such as ritual[51][52]) and raw materials, as early as 120,000 years ago in Middle Paleolithic.[25] Inter-band trade may have appeared during the Middle Paleolithic because trade between bands would have helped ensure their survival by allowing them to exchange resources and commodities such as raw materials during times of relative scarcity (i.e. famine, drought).[25] Like in modern hunter-gatherer societies, individuals in Paleolithic societies may have been subordinate to the band as a whole.[21][22] Both Neanderthals and modern humans took care of the elderly members of their societies during the Middle and Upper Paleolithic.[25]

Some sources claim that most Middle and Upper Paleolithic societies were possibly fundamentally egalitarian[3][22][38][53] and may have rarely or never engaged in organized violence between groups (i.e. war).[38][54][55][56]
Some Upper Paleolithic societies in resource-rich environments (such as societies in Sungir, in what is now Russia) may have had more complex and hierarchical organization (such as tribes with a pronounced hierarchy and a somewhat formal division of labor) and may have engaged in endemic warfare.[38][57] Some argue that there was no formal leadership during the Middle and Upper Paleolithic. Like contemporary egalitarian hunter-gatherers such as the Mbuti pygmies, societies may have made decisions by communal consensus decision making rather than by appointing permanent rulers such as chiefs and monarchs.[6] Nor was there a formal division of labor during the Paleolithic. Each member of the group was skilled at all tasks essential to survival, regardless of individual abilities. Theories to explain the apparent egalitarianism have arisen, notably the Marxist concept of primitive communism.[58][59] Christopher Boehm (1999) has hypothesized that egalitarianism may have evolved in Paleolithic societies because of a need to distribute resources such as food and meat equally to avoid famine and ensure a stable food supply.[60] Raymond C. Kelly speculates that the relative peacefulness of Middle and Upper Paleolithic societies resulted from a low population density, cooperative relationships between groups such as reciprocal exchange of commodities and collaboration on hunting expeditions, and because the invention of projectile weapons such as throwing spears provided less incentive for war, because they increased the damage done to the attacker and decreased the relative amount of territory attackers could gain.[56] However, other sources claim that most Paleolithic groups may have been larger, more complex, sedentary and warlike than most contemporary hunter-gatherer societies, due to occupying more resource-abundant areas than most modern hunter-gatherers who have been pushed into more marginal habitats by agricultural societies.[61]

Anthropologists have typically assumed that in Paleolithic societies, women were responsible for gathering wild plants and firewood, and men were responsible for hunting and scavenging dead animals.[3][38] However, analogies to existent hunter-gatherer societies such as the Hadza people and the Aboriginal Australians suggest that the sexual division of labor in the Paleolithic was relatively flexible. Men may have participated in gathering plants, firewood and insects, and women may have procured small game animals for consumption and assisted men in driving herds of large game animals (such as woolly mammoths and deer) off cliffs.[38][55] Additionally, recent research by anthropologist and archaeologist Steven Kuhn from the University of Arizona is argued to support that this division of labor did not exist prior to the Upper Paleolithic and was invented relatively recently in human pre-history.[62][63] Sexual division of labor may have been developed to allow humans to acquire food and other resources more efficiently.[63] Possibly there was approximate parity between men and women during the Middle and Upper Paleolithic, and that period may have been the most gender-equal time in human history.[54][64][65] Archaeological evidence from art and funerary rituals indicates that a number of individual women enjoyed seemingly high status in their communities, and it is likely that both sexes participated in decision making.[65] The earliest known Paleolithic shaman (c. 30,000 BP) was female.[66]Jared Diamond suggests that the status of women declined with the adoption of agriculture because women in farming societies typically have more pregnancies and are expected to do more demanding work than women in hunter-gatherer societies.[67] Like most contemporary hunter-gatherer societies, Paleolithic and the Mesolithic groups probably followed mostly matrilineal and ambilineal descent patterns; patrilineal descent patterns were probably rarer than in the Neolithic.[34][52]

Lower Paleolithic Acheulean tool users, according to Robert G. Bednarik, began to engage in symbolic behavior such as art around 850,000 BP. They decorated themselves with beads and collected exotic stones for aesthetic, rather than utilitarian qualities.[71] According to him, traces of the pigment ochre from late Lower Paleolithic Acheulean archaeological sites suggests that Acheulean societies, like later Upper Paleolithic societies, collected and used ochre to create rock art.[71] Nevertheless, it is also possible that the ochre traces found at Lower Paleolithic sites is naturally occurring.[72]

Vincent W. Fallio interprets Lower and Middle Paleolithic marking on rocks at sites such as Bilzingsleben (such as zigzagging lines) as accounts or representations of altered states of consciousness[73] though some other scholars interpret them as either simple doodling or as the result of natural processes.

Upper Paleolithic humans produced works of art such as cave paintings, Venus figurines, animal carvings, and rock paintings.[74] Upper Paleolithic art can be divided into two broad categories: figurative art such as cave paintings that clearly depicts animals (or more rarely humans); and nonfigurative, which consists of shapes and symbols.[74] Cave paintings have been interpreted in a number of ways by modern archaeologists. The earliest explanation, by the prehistorian Abbe Breuil, interpreted the paintings as a form of magic designed to ensure a successful hunt.[75] However, this hypothesis fails to explain the existence of animals such as saber-toothed cats and lions, which were not hunted for food, and the existence of half-human, half-animal beings in cave paintings. The anthropologist David Lewis-Williams has suggested that Paleolithic cave paintings were indications of shamanistic practices, because the paintings of half-human, half-animal paintings and the remoteness of the caves are reminiscent of modern hunter-gatherer shamanistic practices.[75] Symbol-like images are more common in Paleolithic cave paintings than are depictions of animals or humans, and unique symbolic patterns might have been trademarks that represent different Upper Paleolithic ethnic groups.[76]Venus figurines have evoked similar controversy. Archaeologists and anthropologists have described the figurines as representations of goddesses, pornographic imagery, apotropaic amulets used for sympathetic magic, and even as self-portraits of women themselves.[38][77]

R. Dale Guthrie[78] has studied not only the most artistic and publicized paintings, but also a variety of lower-quality art and figurines, and he identifies a wide range of skill and ages among the artists. He also points out that the main themes in the paintings and other artifacts (powerful beasts, risky hunting scenes and the over-sexual representation of women) are to be expected in the fantasies of adolescent males during the Upper Paleolithic.

The "Venus" figurines have been theorized, not universally, as representing a mother goddess; the abundance of such female imagery has inspired the theory that Paleolithic (and later Neolithic) societies centered their religion and societies around women. Adherents of the theory include archaeologist Marija Gimbutas and feminist scholar Merlin Stone, the author of the 1976 book When God Was a Woman.[79][80] Other explanations for the purpose of the figurines have been proposed, such as Catherine McCoid and LeRoy McDermott's hypothesis that they were self-portraits of woman artists[77] and R.Dale Gutrie's hypothesis that served as "stone age pornography".

The origins of music during the Paleolithic are unknown. The earliest forms of music probably did not use musical instruments other than the human voice and/or natural objects such as rocks. This early music would not have left an archaeological footprint. Music may have developed from rhythmic sounds produced by daily chores, for example, cracking open nuts with stones. Maintaining a rhythm while working may have helped people to become more efficient at daily activities.[81] An alternative theory originally proposed by Charles Darwin explains that music may have begun as a hominin mating strategy. Bird and other animal species produce music such as calls to attract mates.[82] This hypothesis is generally less accepted than the previous hypothesis, but nonetheless provides a possible alternative. Another explanation is that humans began to make music simply because it pleased them.

Upper Paleolithic (and possibly Middle Paleolithic)[83] humans used flute-like bone pipes as musical instruments,[38][84] and music may have played a large role in the religious lives of Upper Paleolithic hunter-gatherers. As with modern hunter-gatherer societies, music may have been used in ritual or to help induce trances. In particular, it appears that animal skin drums may have been used in religious events by Upper Paleolithic shamans, as shown by the remains of drum-like instruments from some Upper Paleolithic graves of shamans and the ethnographic record of contemporary hunter-gatherer shamanic and ritual practices.[66][74]

According to James B. Harrod humankind first developed religious and spiritual beliefs during the Middle Paleolithic or Upper Paleolithic.[85] Controversial scholars of prehistoric religion and anthropology, James Harrod and Vincent W. Fallio, have recently proposed that religion and spirituality (and art) may have first arisen in Pre-Paleolithic chimpanzees[86] or Early Lower Paleolithic (Oldowan) societies.[73][87] According to Fallio, the common ancestor of chimpanzees and humans experienced altered states of consciousness and partook in ritual, and ritual was used in their societies to strengthen social bonding and group cohesion.[73]

Middle Paleolithic humans' use of burials at sites such as Krapina, Croatia (c. 130,000 BP) and Qafzeh, Israel (c. 100,000 BP) have led some anthropologists and archaeologists, such as Philip Lieberman, to believe that Middle Paleolithic humans may have possessed a belief in an afterlife and a "concern for the dead that transcends daily life".[5] Cut marks on Neanderthal bones from various sites, such as Combe-Grenal and Abri Moula in France, suggest that the Neanderthals—like some contemporary human cultures—may have practiced ritual defleshing for (presumably) religious reasons. According to recent archaeological findings from Homo heidelbergensis sites in Atapuerca, humans may have begun burying their dead much earlier, during the late Lower Paleolithic; but this theory is widely questioned in the scientific community.

Likewise, some scientists have proposed that Middle Paleolithic societies such as Neanderthal societies may also have practiced the earliest form of totemism or animal worship, in addition to their (presumably religious) burial of the dead. In particular, Emil Bächler suggested (based on archaeological evidence from Middle Paleolithic caves) that a bearcult was widespread among Middle Paleolithic Neanderthals.[88] A claim that evidence was found for Middle Paleolithic animal worship c. 70,000 BCE originates from the Tsodilo Hills in the African Kalahari desert has been denied by the original investigators of the site.[89] Animal cults in the Upper Paleolithic, such as the bear cult, may have had their origins in these hypothetical Middle Paleolithic animal cults.[90] Animal worship during the Upper Paleolithic was intertwined with hunting rites.[90] For instance, archaeological evidence from art and bear remains reveals that the bear cult apparently involved a type of sacrificial bear ceremonialism, in which a bear was sliced with arrows, finished off by a blast in the lungs, and ritualistically worshipped near a clay bear statue covered by a bear fur with the skull and the body of the bear buried separately.[90] Barbara Ehrenreich controversially theorizes that the sacrificial hunting rites of the Upper Paleolithic (and by extension Paleolithic cooperative big-game hunting) gave rise to war or warlike raiding during the following Epipaleolithic and Mesolithic or late Upper Paleolithic.[55]

The existence of anthropomorphic images and half-human, half-animal images in the Upper Paleolithic may further indicate that Upper Paleolithic humans were the first people to believe in a pantheon of gods or supernatural beings,[91] though such images may instead indicate shamanistic practices similar to those of contemporary tribal societies.[75] The earliest known undisputed burial of a shaman (and by extension the earliest undisputed evidence of shamans and shamanic practices) dates back to the early Upper Paleolithic era (c. 30,000 BP) in what is now the Czech Republic.[66] However, during the early Upper Paleolithic it was probably more common for all members of the band to participate equally and fully in religious ceremonies, in contrast to the religious traditions of later periods when religious authorities and part-time ritual specialists such as shamans, priests and medicine men were relatively common and integral to religious life.[22] Additionally, it is also possible that Upper Paleolithic religions, like contemporary and historical animistic and polytheistic religions, believed in the existence of a single creator deity in addition to other supernatural beings such as animistic spirits.[92]

Vincent W. Fallio writes that ancestor cults first emerged in complex Upper Paleolithic societies. He argues that the elites of these societies (like the elites of many more contemporary complex hunter-gatherers such as the Tlingit) may have used special rituals and ancestor worship to solidify control over their societies, by convincing their subjects that they possess a link to the spirit world that also gives them control over the earthly realm.[73]Secret societies may have served a similar function in these complex quasi-theocratic societies, by dividing the religious practices of these cultures into the separate spheres of folk religion and elite religion.[73]

Religion was possibly apotropaic; specifically, it may have involved sympathetic magic.[38] The Venus figurines, which are abundant in the Upper Paleolithic archaeological record, provide an example of possible Paleolithic sympathetic magic, as they may have been used for ensuring success in hunting and to bring about fertility of the land and women.[3] The Upper Paleolithic Venus figurines have sometimes been explained as depictions of an earth goddess similar to Gaia, or as representations of a goddess who is the ruler or mother of the animals.[90][93] James Harrod has described them as representative of female (and male) shamanistic spiritual transformation processes.[94]

Paleolithic hunting and gathering people ate varying proportions of vegetables (including tubers and roots), fruit, seeds (including nuts and wild grass seeds) and insects, meat, fish, and shellfish.[96][97] However, there is little direct evidence of the relative proportions of plant and animal foods.[98] Although the term "paleolithic diet", without references to a specific timeframe or locale, is sometimes used with an implication that most humans shared a certain diet during the entire era, that is not entirely accurate. The Paleolithic was an extended period of time, during which multiple technological advances were made, many of which had impact on human dietary structure. For example, humans probably did not possess the control of fire until the Middle Paleolithic,[99] or tools necessary to engage in extensive fishing.[citation needed] On the other hand, both these technologies are generally agreed to have been widely available to humans by the end of the Paleolithic (consequently, allowing humans in some regions of the planet to rely heavily on fishing and hunting). In addition, the Paleolithic involved a substantial geographical expansion of human populations. During the Lower Paleolithic, ancestors of modern humans are thought to have been constrained to Africa east of the Great Rift Valley. During the Middle and Upper Paleolithic, humans greatly expanded their area of settlement, reaching ecosystems as diverse as New Guinea and Alaska, and adapting their diets to whatever local resources were available.

Another view is that until the Upper Paleolithic, humans were frugivores (fruit eaters) who supplemented their meals with carrion, eggs, and small prey such as baby birds and mussels, and only on rare occasions managed to kill and consume big game such as antelopes.[100] This view is supported by studies of higher apes, particularly chimpanzees. Chimpanzees are the closest to humans genetically, sharing more than 96% of their DNA code with humans, and their digestive tract is functionally very similar to that of humans.[101] Chimpanzees are primarily frugivores, but they could and would consume and digest animal flesh, given the opportunity. In general, their actual diet in the wild is about 95% plant-based, with the remaining 5% filled with insects, eggs, and baby animals.[102][103] In some ecosystems, however, chimpanzees are predatory, forming parties to hunt monkeys.[104] Some comparative studies of human and higher primate digestive tracts do suggest that humans have evolved to obtain greater amounts of calories from sources such as animal foods, allowing them to shrink the size of the gastrointestinal tract relative to body mass and to increase the brain mass instead.[105][106]

Anthropologists have diverse opinions about the proportions of plant and animal foods consumed. Just as with still existing hunters and gatherers, there were many varied "diets"—in different groups—and also varying through this vast amount of time. Some paleolithic hunter-gatherers consumed a significant amount of meat and possibly obtained most of their food from hunting,[107] while others are shown as a primarily plant-based diet,[62] Most, if not all, are believed to have been opportunistic omnivores.[108] One hypothesis is that carbohydrate tubers (plant underground storage organs) may have been eaten in high amounts by pre-agricultural humans.[109][110][111][112] It is thought that the Paleolithic diet included as much as 1.65–1.9 kg (3.6–4.2 lb) per day of fruit and vegetables.[113] The relative proportions of plant and animal foods in the diets of Paleolithic people often varied between regions, with more meat being necessary in colder regions (which weren't populated by anatomically modern humans until c. 30,000 – c. 50,000 BP).[114] It is generally agreed that many modern hunting and fishing tools, such as fish hooks, nets, bows, and poisons, weren't introduced until the Upper Paleolithic and possibly even Neolithic.[34] The only hunting tools widely available to humans during any significant part of the Paleolithic were hand-held spears and harpoons. There's evidence of Paleolithic people killing and eating seals and elands as far as c. 100,000 BP. On the other hand, buffalo bones found in African caves from the same period are typically of very young or very old individuals, and there's no evidence that pigs, elephants, or rhinos were hunted by humans at the time.[115]

Paleolithic peoples suffered less famine and malnutrition than the Neolithic farming tribes that followed them.[21][116] This was partly because Paleolithic hunter-gatherers accessed a wider variety natural foods, which allowed them a more nutritious diet and a decreased risk of famine.[21][23][67] Many of the famines experienced by Neolithic (and some modern) farmers were caused or amplified by their dependence on a small number of crops.[21][23][67] It is thought that wild foods can have a significantly different nutritional profile than cultivated foods.[117] The greater amount of meat obtained by hunting big game animals in Paleolithic diets than Neolithic diets may have also allowed Paleolithic hunter-gatherers to enjoy a more nutritious diet than Neolithic agriculturalists.[116] It has been argued that the shift from hunting and gathering to agriculture resulted in an increasing focus on a limited variety of foods, with meat likely taking a back seat to plants.[118] It is also unlikely that Paleolithic hunter-gatherers were affected by modern diseases of affluence such as type 2 diabetes, coronary heart disease, and cerebrovascular disease, because they ate mostly lean meats and plants and frequently engaged in intense physical activity,[119][120] and because the average lifespan was shorter than the age of common onset of these conditions.[121][122]

Large-seeded legumes were part of the human diet long before the Neolithic Revolution, as evident from archaeobotanical finds from the Mousterian layers of Kebara Cave, in Israel.[123] There is evidence suggesting that Paleolithic societies were gathering wild cereals for food use at least as early as 30,000 years ago.[124] However, seeds—such as grains and beans—were rarely eaten and never in large quantities on a daily basis.[125] Recent archaeological evidence also indicates that winemaking may have originated in the Paleolithic, when early humans drank the juice of naturally fermented wild grapes from animal-skin pouches.[95] Paleolithic humans consumed animal organ meats, including the livers, kidneys, and brains. Upper Paleolithic cultures appear to have had significant knowledge about plants and herbs and may have, albeit very rarely, practiced rudimentary forms of horticulture.[126] In particular, bananas and tubers may have been cultivated as early as 25,000 BP in southeast Asia.[61] Late Upper Paleolithic societies also appear to have occasionally practiced pastoralism and animal husbandry, presumably for dietary reasons. For instance, some European late Upper Paleolithic cultures domesticated and raised reindeer, presumably for their meat or milk, as early as 14,000 BP.[44] Humans also probably consumed hallucinogenic plants during the Paleolithic.[3] The Aboriginal Australians have been consuming a variety of native animal and plant foods, called bushfood, for an estimated 60,000 years, since the Middle Paleolithic.

Large game animals such as deer were an important source of protein in Middle and Upper Paleolithic diets.

People during the Middle Paleolithic, such as the Neanderthals and Middle Paleolithic Homo sapiens in Africa, began to catch shellfish for food as revealed by shellfish cooking in Neanderthal sites in Italy about 110,000 years ago and in Middle Paleolithic Homo sapiens sites at Pinnacle Point, Africa around 164,000 BP.[38][127] Although fishing only became common during the Upper Paleolithic,[38][128]fish have been part of human diets long before the dawn of the Upper Paleolithic and have certainly been consumed by humans since at least the Middle Paleolithic.[47] For example, the Middle Paleolithic Homo sapiens in the region now occupied by the Democratic Republic of the Congo hunted large 6 ft (1.8 m)-long catfish with specialized barbed fishing points as early as 90,000 years ago.[38][47] The invention of fishing allowed some Upper Paleolithic and later hunter-gatherer societies to become sedentary or semi-nomadic, which altered their social structures.[84] Example societies are the Lepenski Vir as well as some contemporary hunter-gatherers, such as the Tlingit. In some instances (at least the Tlingit), they developed social stratification, slavery, and complex social structures such as chiefdoms.[34]

Anthropologists such as Tim White suggest that cannibalism was common in human societies prior to the beginning of the Upper Paleolithic, based on the large amount of “butchered human" bones found in Neanderthal and other Lower/Middle Paleolithic sites.[129] Cannibalism in the Lower and Middle Paleolithic may have occurred because of food shortages.[130] However, it may have been for religious reasons, and would coincide with the development of religious practices thought to have occurred during the Upper Paleolithic.[90][131] Nonetheless, it remains possible that Paleolithic societies never practiced cannibalism, and that the damage to recovered human bones was either the result of excarnation or predation by carnivores such as saber-toothed cats, lions, and hyenas.[90]

A modern-day diet known as the Paleolithic diet exists, based on restricting consumption to the foods presumed to be available to anatomically modern humans prior to the advent of settled agriculture.[132]

Glyptodon
–
Glyptodon was a genus of large, armored mammal of the subfamily Glyptodontinae – relatives of armadillos – that lived during the Pleistocene epoch. It was roughly the size and weight as a Volkswagen Beetle. In 2016 an analysis of Doedicurus mtDNA found it was, in fact, for this reason, glyptodonts and all armadillos but Dasypus were relocated to a new family, Chlamyphoridae. Although Darwin is said to have found the first fossils of glyptodontines, the then unnamed Glyptodon was briefly mentioned in a letter from Don Damsio Laranaga. It was about seven pounds, and maybe six or eight inches wide, at the time, the discovery was believed to have belonged to Megatherium, a type of giant ground sloth. A man named Sellow found some carapace plates in three-foot deep clay in Uruguay four years later, although some believed that the armor resembled that of the modern armadillo, the popular opinion was the Megatherium theory. It was not until Professor E. D’Alton said that all the peculiarities of the former may be paralleled to the latter He concluded that the fossils belonged to some version of an armadillo. However, since a full skeleton was not available at the time and this uncertainty in the fossil remains continued until a man named Dr. Lund identified the remains as a new genus in his 1837 memoir. When scholars first acknowledged the genus Glyptodon, there was not a consensus on its name, in 1837 Dr. Lund, a professor who wrote a memoir on Brazil’s ancient fauna, suggested these creatures be recognized as the new genus Hoplophorus. In 1838, another scientist, Professor Bronn, published in the edition of his book Lethaea Geognostica a proposal for the new genus to be called Chlamydotherium. In Professor D’Alton’s 1839 memoir, it was called Pachypus, the director at the Museum of Natural History in Dijon at the time, M. L. Nodot, had named the genus Schistopleuron and it was finally given a single name when English scholar Richard Owen noticed the similarities of the genera his colleagues were describing in their publications. Owen realized they were all the genus from their depictions. He decided on Glyptodon, which means grooved or carved tooth, the name was originally coined by Sir Woodbine Parish, the man who had sent some Glyptodon fossils to Europe. Those fragments of carapace and bones he sent had been studied at the time and had assisted in the recognition of the new genus. After unifying the name of genus, Owen continued working on its taxonomy. In 1845, after analyzing the fossils of his colleagues, he named four species within the genus, G. clavipes, G. reticulatus, G. ornatus, Glyptodon is part of the superorder of placental mammals known as Xenarthra. This clade of mammals also includes anteaters, tree sloths, armadillos and their remains have been found in Brazil, Uruguay and Argentina

Oldowan
–
The Oldowan, sometimes spelled Olduwan, is the earliest widespread stone tool archaeological industry in prehistory. Oldowan tools were used during the Lower Paleolithic period,2.6 million years ago up until 1.7 million years ago, by ancient hominids across much of Africa, South Asia and this technological industry was followed by the more sophisticated Acheulean industry. The term Oldowan is taken from the site of Olduvai Gorge in Tanzania, classification of Oldowan tools is still somewhat contentious. Mary Leakey was the first to create a system to classify Oldowan assemblages, the system included choppers, scrapers, and pounders. However, more recent classifications of Oldowan assemblages have been made that focus primarily on manufacture due to the nature of assuming use from stone artefacts. An example is Isaac et al. s tri-modal categories of Flaked Pieces, Detached Pieces, Pounded Pieces, Oldowan tools are sometimes called pebble tools, so named because the blanks chosen for their production already resemble, in pebble form, the final product. It is not known for sure which hominin species actually created and used Oldowan tools and its emergence is often associated with the species Australopithecus garhi and its flourishing with early species of Homo such as H. habilis and H. ergaster. Early Homo erectus appears to inherit Oldowan technology and refines it into the Acheulean industry beginning 1.7 million years ago, the oldest known Oldowan tools have been found in Gona, Ethiopia, and are dated to about 2.6 mya. The use of tools by apes including chimpanzees and orangutans can be used to argue in favour of tool-use as a feature of the hominin family. Tools made from bone, wood, or other materials were therefore in all probability used before the Oldowan. Oldowan stone tools are simply the oldest recognisable tools which have preserved in the archaeological record. There is a flourishing of Oldowan tools in eastern Africa, spreading to southern Africa, at 1.7 mya. the first Acheulean tools appear even as Oldowan assemblages continue to be produced. Both technologies are found in the same areas, dating to the same time periods. This realisation required a rethinking of old cultural sequences in which the more advanced Acheulean was supposed to have succeeded the Oldowan. Sometime before 1.8 mya Homo erectus had spread outside of Africa, reaching as far east as Java by 1.8 mya, in these newly colonised areas, no Acheulean assemblages have been found. In China, only Mode 1 Oldowan assemblages were produced, while in Indonesia stone tools from this age are unknown, by 1.8 mya early Homo was present in Europe, as shown by the discovery of fossil remains and Oldowan tools in Dmanisi, Georgia. Remains of their activities have also excavated in Spain at sites in the Guadix-Baza basin. Most early European sites yield Mode 1 or Oldowan assemblages, the earliest Acheulean sites in Europe only appear around 0.5 mya

Acheulean
–
Acheulean, from the French acheuléen, is an archaeological industry of stone tool manufacture characterized by distinctive oval and pear-shaped hand-axes associated with early humans. Acheulean tools were produced during the Lower Palaeolithic era across Africa and much of West Asia, South Asia, and Europe, and are typically found with Homo erectus remains. It is thought that Acheulean technologies first developed in Africa out of the more primitive Oldowan technology as long ago as 1.76 million years ago, Acheulean tools were the dominant technology for the vast majority of human history. The type site for the Acheulean is Saint-Acheul, a suburb of Amiens, the capital of the Somme department in Picardy, john Frere is generally credited as being the first to suggest a very ancient date for Acheulean hand-axes. In 1797, he sent two examples to the Royal Academy in London from Hoxne in Suffolk and his ideas were, however, ignored by his contemporaries, who subscribed to a pre-Darwinian view of human evolution. Following visits to both Abbeville and Saint Acheul by the geologist Joseph Prestwich, the age of the tools was finally accepted, in 1872, Louis Laurent Gabriel de Mortillet described the characteristic hand-axe tools as belonging to LEpoque de St Acheul. The industry was renamed as the Acheulean in 1925, from the Konso Formation of Ethiopia, Acheulean hand-axes are dated to about 1.5 million years ago using radiometric dating of deposits containing volcanic ashes. Acheulean tools in South Asia have also found to be dated as far as 1.5 million years ago. However, the earliest accepted examples of the Acheulean currently known come from the West Turkana region of Kenya and were first described by a French-led archaeology team. These particular Acheulean tools were dated through the method of magnetostratigraphy to about 1.76 million years ago, making them the oldest not only in Africa. The earliest user of Acheulean tools was Homo ergaster, who first appeared about 1.8 million years ago, not all researchers use this formal name, and instead prefer to call these users early Homo erectus. In individual regions, this dating can be refined, in Europe for example. However more recent research demonstrated that hand-axes from Spain were made more than 900,000 years ago, the enormous geographic spread of Acheulean techniques also makes the name unwieldy as it represents numerous regional variations on a similar theme. The term Acheulean does not represent a culture in the modern sense. The very earliest Acheulean assemblages often contain numerous Oldowan-style flakes and core forms and these industries are known as the Developed Oldowan and are almost certainly transitional between the Oldowan and Acheulean. The Mode 1 industries created rough flake tools by hitting a stone with a hammerstone. The resulting flake that broke off would have a sharp edge for cutting. These early toolmakers may also have worked the stone they took the flake from to create chopper cores although there is debate over whether these items were tools or just discarded cores

4.
Mousterian
–
Mousterian is a name given by archaeologists to a style of predominantly flint tools associated primarily with Neanderthals. They date to the Middle Paleolithic, the part of the European Old Stone Age. The culture was named after the site of Le Moustier. Similar flintwork has been all over unglaciated Europe and also the Near East. Handaxes, racloirs and points constitute the industry, sometimes a Levallois technique or another prepared-core technique was employed in making the flint flakes, Mousterian tools that have been found in Europe were made by Neanderthals and date from around 160,000 BP and 40,000 BP. In North Africa and the Near East, Mouseterian tools were produced by anatomically modern humans. In the Levant, for example, assemblages produced by Neanderthals are indistinguishable from those made by Qafzeh type modern humans, possible variants are Denticulate, Charentian named after the Charente region, Typical and the Acheulean Tradition - Type-A and Type-B. The industry continued alongside the new Châtelperronian industry during the 45, Mousterian artifacts have been found in Haua Fteah in Cyrenaica and other sites in Northwest Africa. Contained within a cave in the Syria region, along with a Neanderthaloid skeleton, located in the Haibak valley of Afghanistan. Zagros and Central Iran The archaeological site of Atapuerca, Spain, gorhams Cave in Gibraltar contains Mousterian objects. Uzbekistan has sites of Mousterian culture, including Teshik-Tash, siberia has many sites with Mousterian style implements, eg Denisova Cave.

Upper Paleolithic
–
The Upper Paleolithic is the third and last subdivision of the Paleolithic or Old Stone Age. Very broadly, it dates to between 50,000 and 10,000 years ago, roughly coinciding with the appearance of behavioral modernity, modern humans are believed to have emerged about 195,000 years ago in Africa. Although these humans were modern in anatomy, their lifestyle changed very little from their contemporaries, such as Homo erectus, about 50,000 years ago, there was a marked increase in the diversity of artifacts. In Africa, bone artifacts and the first art appear in the archeological record, between 45,000 and 43,000 years ago, this new tool technology spread with human migration to Europe. The new technology generated an explosion of modern humans which is believed to have contributed to the extinction of the Neanderthals. The Upper Paleolithic has the earliest known evidence of organized settlements, in the form of campsites, artistic work blossomed, with cave painting, petroglyphs, carvings and engravings on bone or ivory. The first evidence of fishing is also noted, from artifacts in places such as Blombos cave in South Africa. More complex social groupings emerged, supported by more varied and reliable food sources and this probably contributed to increasing group identification or ethnicity. By 50, 000–40,000 BP, the first humans set foot in Australia, by 45,000 BP, humans lived at 61° north latitude in Europe. By 30,000 BP, Japan was reached, and by 27,000 BP humans were present in Siberia above the Arctic Circle, at the end of the Upper Paleolithic, a group of humans crossed the Bering land bridge and quickly expanded throughout North and South America. Both Homo erectus and Neanderthals used the same crude stone tools, archaeologist Richard G. Klein, who has worked extensively on ancient stone tools, describes the stone tool kit of archaic hominids as impossible to categorize. It was as if the Neanderthals made stone tools, and were not much concerned about their final forms and he argues that almost everywhere, whether Asia, Africa or Europe, before 50,000 years ago all the stone tools are much alike and unsophisticated. These new stone-tool types have been described as being distinctly differentiated from each other, the invaders, commonly referred to as the Cro-Magnons, left many sophisticated stone tools, carved and engraved pieces on bone, ivory and antler, cave paintings and Venus figurines. The Neanderthals continued to use Mousterian stone tool technology and possibly Chatelperronian technology and these tools disappeared from the archeological record at around the same time the Neanderthals themselves disappeared from the fossil record, about 40,000 years ago. Settlements were often located in valley bottoms, possibly associated with hunting of passing herds of animals. Hunting was important, and caribou/wild reindeer may well be the species of single greatest importance in the anthropological literature on hunting. Technological advances included significant developments in flint tool manufacturing, with industries based on fine blades rather than simpler and shorter flakes, burins and racloirs were used to work bone, antler and hides. Advanced darts and harpoons also appear in period, along with the fish hook, the oil lamp, rope

6.
Aurignacian
–
The Aurignacian culture is an archaeological culture of the Upper Palaeolithic. It is the earliest modern human culture in Europe, and is associated with the immigration of anatomically modern humans from the Near East and it first appeared in Eastern Europe around 43,000 BP, and in Western Europe between 40,000 and 36,000 years BP. It was replaced by the Gravettian culture around 28,000 to 26,000 years ago, the name originates from the type site of Aurignac, Haute-Garonne, which is a town in the south-west of France near Toulouse or Andorra. The oldest undisputed example of figurative art, the Venus of Hohle Fels. It was discovered in September 2008 in a cave at Schelklingen in Baden-Württemberg in southern Germany, the Bacho Kiro site is one of the earliest known Aurignacian burials. The Aurignacian tool industry is characterized by worked bone or antler points with grooves cut in the bottom. Their flint tools include blades and bladelets struck from prepared cores rather than using crude flakes. )The people of this culture also produced some of the earliest known cave art, such as the animal engravings at Trois Freres. They also made pendants, bracelets, and ivory beads, as well as three-dimensional figurines, perforated rods, thought to be spear throwers or shaft wrenches, also are found at their sites. The sophistication and self-awareness demonstrated in the work led archaeologists to consider the makers of Aurignacian artifacts the first modern humans in Europe, human remains and Late Aurignacian artifacts found in juxtaposition support this inference. Although finds of human remains in direct association with Proto-Aurignacian technologies are scarce in Europe. At least three robust, but typically anatomically-modern individuals from the Peștera cu Oase cave in Romania, were dated directly from the bones to ca, although not associated directly with archaeological material, these finds are within the chronological and geographical range of the Early Aurignacian in southeastern Europe. On genetic evidence it has argued that both Aurignacian and the Dabba culture of North Africa came from an earlier big game hunting Aurignacian culture of the Levant. Many 35, 000-year-old animal figurines were discovered in the Vogelherd Cave in Germany, one of the horses, amongst six tiny mammoth and horse ivory figures found previously at Vogelherd, was sculpted as skillfully as any piece found throughout the Upper Paleolithic. The production of ivory beads for body ornamentation was also important during the Aurignacian, there is a notable absence of painted caves, however, which begin to appear within the Solutrean. Typical statuettes consist of women that are called Venus figurines and they emphasize the hips, breasts, and other body parts associated with fertility. Feet and arms are lacking or minimized, one of the most ancient figurines was discovered in 2008 in the Hohle Fels cave in Germany. The figurine has been dated to 35,000 years ago, the oldest undisputed musical instrument was the Hohle Fels Flute discovered in the Hohle Fels cave in Germanys Swabian Alb in 2008. The flute is made from a wing bone perforated with five finger holes

Prehistory
–
Prehistory means literally before history, from the Latin word for before, præ, and Greek ιστορία. Neighbouring civilisations were the first to follow, most other civilisations reached the end of prehistory during the Iron Age. The period when a culture is written about by others, but has not developed its own writing is known as the protohistory of the culture. By definition, there are no records from human prehistory. Clear techniques for dating were not well-developed until the 19th century and this article is concerned with human prehistory as defined here above. There are separate articles for the history of the Earth. However, for the race as a whole, prehistory ends when recorded history begins with the accounts of the ancient world around the 4th millennium BC. For example, in Egypt it is accepted that prehistory ended around 3200 BC, whereas in New Guinea the end of the prehistoric era is set much more recently. The three-age system is the periodization of prehistory into three consecutive time periods, named for their respective predominant tool-making technologies, Stone Age Bronze Age Iron Age. The notion of prehistory began to surface during the Enlightenment in the work of antiquarians who used the word primitive to describe societies that existed before written records, the first use of the word prehistory in English, however, occurred in the Foreign Quarterly Review in 1836. The main source for prehistory is archaeology, but some scholars are beginning to more use of evidence from the natural and social sciences. This view has been articulated by advocates of deep history, human population geneticists and historical linguists are also providing valuable insight for these questions. Human prehistory differs from history not only in terms of its chronology, restricted to material processes, remains and artifacts rather than written records, prehistory is anonymous. Because of this, reference terms that use, such as Neanderthal or Iron Age are modern labels with definitions sometimes subject to debate. Palaeolithic means Old Stone Age, and begins with the first use of stone tools, the Paleolithic is the earliest period of the Stone Age. The early part of the Palaeolithic is called the Lower Palaeolithic, evidence of control of fire by early humans during the Lower Palaeolithic Era is uncertain and has at best limited scholarly support. The most widely accepted claim is that H. erectus or H. ergaster made fires between 790,000 and 690,000 BP in a site at Bnot Yaakov Bridge, Israel. The use of fire enabled early humans to cook food, provide warmth, Early Homo sapiens originated some 200,000 years ago, ushering in the Middle Palaeolithic

8.
Knapping
–
The original Germanic term knopp meant strike, shape, or work, so it could theoretically have referred equally well to making a statue or dice. Modern usage is specific, referring almost exclusively to the hand-tool pressure-flaking process pictured. Flintknapping or knapping is done in a variety of ways depending on the purpose of the final product, for stone tools and flintlock strikers, chert is worked using a fabricator such as a hammerstone to remove lithic flakes from a nucleus or core of tool stone. Stone tools can then be refined using wood, bone. For building work a hammer or pick is used to split chert nodules supported on the lap, often the chert nodule will be split in half to create two cherts with a flat circular face for use in walls constructed of lime. More sophisticated knapping is employed to produce almost perfect cubes which are used as bricks, there are many different methods of shaping stone into useful tools. Early knappers could have used hammers made of wood or antler to shape stone tools. The factors that contribute to the results are varied, but the EPA indeed influences many attributes, such as length, thickness. Hard hammer techniques are used to remove large flakes of stone, early knappers and hobbyists replicating their methods often use cobbles of very hard stone, such as quartzite. This technique can be used by flintknappers to remove broad flakes that can be made into smaller tools and this method of manufacture is believed to have been used to make some of the earliest stone tools ever found, some of which date from over 2 million years ago. Soft hammer techniques are more precise than hard hammer methods of shaping stone, soft hammer techniques allow a knapper to shape a stone into many different kinds of cutting, scraping, and projectile tools. These soft hammer techniques also produce longer, thinner flakes, potentially allowing for material conservation or a lighter lithic tool kit to be carried by mobile societies, pressure flaking involves removing narrow flakes along the edge of a stone tool. This technique is used to do detailed thinning and shaping of a stone tool. Pressure flaking involves putting an amount of force across a region on the edge of the tool. The major advantage of using soft metals rather than wood or bone is that the metal punches wear down less and are likely to break under pressure. Archaeologists usually undertake the task so that they can understand how prehistoric stone tools were made. Knapping is often learned by outdoorsmen, such as British bushcraft exponent Ray Mears, knapping gun flints, used by flintlock firearms was formerly a major industry in flint bearing locations, such as Brandon in Suffolk, England and the small towns of Meusnes and Couffy in France. Meusnes has a museum dedicated to the industry

Leather
–
Leather is a durable and flexible material created by tanning animal rawhide and skin, often cattle hide. It can be produced at manufacturing scales ranging from cottage industry to heavy industry, people use leather to make various goods—including clothing, bookbinding, leather wallpaper, and as a furniture covering. It is produced in a variety of types and styles. Several tanning processes transform hides and skins into leather, Chrome-tanned leather, invented in 1858, is tanned using chromium sulfate and it is more supple and pliable than vegetable-tanned leather and does not discolor or lose shape as drastically in water as vegetable-tanned. It is also known as wet-blue for its color derived from the chromium, more exotic colors are possible when using chrome tanning. The chrome tanning method usually only takes a day to finish, and it is reported that chrome-tanned leather adds up to 80% of the global leather supply. Vegetable-tanned leather is tanned using tannins and other found in different vegetable matter, such as tree bark prepared in bark mills, wood, leaves, fruits. It is supple and brown in color, with the exact shade depending on the mix of chemicals and it is the only form of leather suitable for use in leather carving or stamping. Vegetable-tanned leather is not stable in water, it tends to discolor, so if left to soak and then dried it shrinks, in hot water, it shrinks drastically and partly congeals—becoming rigid, and eventually brittle. Boiled leather is an example of this, where the leather has been hardened by being immersed in hot water, historically, it was occasionally used as armour after hardening, and it has also been used for book binding. Aldehyde-tanned leather is tanned using glutaraldehyde or oxazolidine compounds and this is the leather that most tanners refer to as wet-white leather due to its pale cream or white color. It is the type of chrome-free leather, often seen in shoes for infants. Formaldehyde tanning is another aldehyde tanning method, brain-tanned leathers fall into this category, and are exceptionally water absorbent. Brain tanned leathers are made by a process that uses emulsified oils, often those of animal brains such as deer, cattle. They are known for their softness and washability. Chamois leather also falls into the category of aldehyde tanning, and like brain tanning, produces a porous, chamois leather is made using marine oils that oxidize easily to produce the aldehydes that tan the leather to color it. Rose-tanned leather is a variation of oil tanning and brain tanning. Rose-tanned leather tanned leaves a powerful rose fragrance even years from when it is manufactured and it has been called the most valuable leather on earth, but this is mostly due to the high cost of rose otto and its labor-intensive tanning process

Paleo-Indians
–
The prefix paleo- comes from the Greek adjective palaios, meaning old or ancient. The term Paleo-Indians applies specifically to the period in the Western Hemisphere and is distinct from the term Paleolithic. Evidence suggests big-animal hunters crossed the Bering Strait from Eurasia into North America over a land and ice bridge, small isolated groups of hunter-gatherers migrated alongside herds of large herbivores far into Alaska. From c. 16,500 – c. 13,500 BCE, ice-free corridors developed along the Pacific coast and this allowed animals, followed by humans, to migrate south into the interior. The people went on foot or used primitive boats along the coastline, the precise dates and routes of the peopling of the New World are subject to ongoing debate. Stone tools, particularly projectile points and scrapers, are the evidence of the earliest human activity in the Americas. Crafted lithic flaked tools are used by archaeologists and anthropologists to classify cultural periods, scientific evidence links Indigenous Americans to Asian peoples, specifically eastern Siberian populations. There is evidence for at least two separate migrations, between 8000–7000 BCE the climate stabilized, leading to a rise in population and lithic technology advances, resulting in more sedentary lifestyle. The specifics of Paleo-Indian migration to and throughout the Americas, including the dates and routes traveled, are subject to ongoing research. These people are believed to have followed herds of now-extinct pleistocene megafauna along ice-free corridors that stretched between the Laurentide and Cordilleran ice sheets, another route proposed is that, either on foot or using primitive boats, they migrated down the Pacific coast to South America. Evidence of the latter would since have been covered by a sea rise of hundreds of meters following the last ice age. Archaeologists contend that Paleo-Indians migration out of Beringia, ranges from c. 40,000 – c. 16,500 years ago and this time range is a source of debate and promises to continue as such for years to come. However, alternative theories about the origins of Paleoindians exist, including migration from Europe, the Paleo-Indian would eventually flourish all over the Americas. These peoples were spread over a geographical area, thus there were regional variations in lifestyles. However, all the groups shared a common style of stone tool production, making knapping styles. Food would have been plentiful during the few months of the year. Lakes and rivers were teeming with many species of fish, birds, nuts, berries and edible roots could be found in the forests and marshes. The fall would have been a time because foodstuffs would have to be stored

Acheulean (also Acheulian and Mode II), from the French acheuléen, is an archaeological industry of stone tool …

A reconstruction of Homo habilis at the Westfälisches Museum für Archäologie, Herne. It is thought that Acheulean technologies first developed in Africa out of the more primitive Oldowan technology as long as 1.76 million years ago, by Homo habilis.

This is a drawing of a replica of an Acheulean hand-axe found during the Lower Paleolithic period. The raw material this tool is made of in this drawing is black obsidian and is even worked on both sides.
